JAR-SEALER.

Application field May 10, 1915. Serial No. 27,157.

To all whom it may concern:

Be it known that I, MASON G. MCCOY, a citizen of the United States of America, residing at lVaitsburg, in the county of WValla Walla and State of Washington, have in vented certain new and useful Improvements in Jar-Sealers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a jar sealer and has for its principal object the production of asimple and eflicient means for detachably retaining the cap of a jar in a binding engagement with the upper portions of the jar, thereby preventing the escaping or the spoiling of the contents of the jar.

Another object of this invention is the production of ajar sealer which is so constructed as to detachably engage the upper portions of the jar as well as the cap for positively binding the cap in engagement with the jar and which is provided with 7 spring clips which are adapted to move to a closed position as the jar sealer is tightened upon the cap, thereby positively preventlng the spring clips from moving from engagement with the lugs, after the jar has been sealed.

With these and other objects in view, this invention consists of certain novel combinations, constructions, and arrangements of parts, as will be hereinafter fullydescribed and claimed.

In the accompanying drawing :.Figure 1 is a side elevation of the jar sealer, in use. Fig. 2 is a top plan view of the invention. Fig. 3 is a section taken on the line 33 of Fig. 1. Fig. 4 is a fragmentary perspective view of portions of the jar sealer illustrating particularly one of the spring clips.

Referring to the accompanying drawing by numerals it will be seen that the device is adapted to be used in connection with a jar 1 which is preferably formed of glass, china, or similar material. This jar 1 is provided with a thickened upper portion 2 which extends upwardly to form an annular upstanding collar 3 thereby forming a seat A. The gasket 5 is positioned upon the seat A within the collar 3 and upon this gasket 5 the cap 6 is adapted to rest. It will be seen that by allowing the cap 6 to fit within the collar 3 it will be held against displacement after the jar has been closed by means of the cap. The lugs 7 are formed integral upon the thickened portion 20f the jar and these lugs 7 extend sllghtly downwardly to provlde the slanting-under faces 8 which exQ tend to the outer surfaces of the thickened portion 2. The portions used for positively binding the cap 6 upon the gasket 5 comprise the top plate 9 having a central opening 10 through which the set screw 11 is adapted to pass. The cap 6 is provided with the transverse bar 12 in its upper portion and the lower end of the set screw 11 is adapted who passed through theopening 10 so as to bear upon this bar 12 for positively binding the cap in position, thereby preventing the spilling or escaping of the contents of the jar 1..

It will be seen that by having the bar 12 extending entirely across the upper portion of the cap 6 the pressure imparted tothe cap 6 by means of the screwll will be evenly distributed over the cap at all portions and thereby lessen the danger of the cap becoming cracked or broken, owing to the excessive pressure at one point thereof.

The spring clipsare adapted to be carried 1 by the plate 9 and each spring clip is formed of a single strip of material which is rolled Specification of Letters Patent. Patented Mar. 7, 1916. I

intermediate its ends to provide the sleeve 13 whereupon extend the arms 14 within which are formed the registering apertures 15. The plate 9 is provided with integral lugs 16 formed upon its outer periphery, these lugs being formed at spaced distances apart. Each lug'16 is'provided with a lon-' gitudinal slot 17 through which one of the arms 14 is adapted to pass so as to allow the rolled sleeve 13 to fit upon the lug and be carried by the plate as clearly shown in Fig. 4c. When the device is first assembled, the spring clips will engage the lugs 7 of the thickened portion 2 as indicated in dotted lines in Fig. 3. In this figure it will be seen that the two arms of each spring clip are extending at spaced distances apart as indicated also by Fig. 4. At this time, the plate 9 is also much closer to the upper portions of the cap 6 than when the device is adjusted. The set screw 11 may then be rotated so as to draw the plate 9 upwardly and with this operation the spring clips will also be drawn upwardly so that the portions of the clip adjacent the apertures 15 will ride upon the lower slanting surfaces of each particular lug 7. As the clipsride upon the slanting surfaces of the lugs 7, they will be drawn close together, as shown in Figs. 1

and 3 and at this time the plate 9 will also be at a greater distance than when the set screw 11 is first rotated. By this amount of pressure upon the cap 6 it will be held so as to make the closure for the jar airtight and at the same time, the clips fitting upon the slanting lugs will prevent their accidental displacement from upon the lugs, after the sealer has been tightened.

It will be seen that by constructing the spring clips of resilient material, whenever the screw is. rotated so as to relieve the. tension upon the arms 14:, they will spring apart, as shown in dotted .lines in Fig. 8. Therefore, a person may very easily grip the outer arm of each clip for readily removing the clips from engagement with said slanting lugs. Furthermore,-by having the arms extending from both sides of each sleeve it will be impossible for the sleeve to be pulled open when pressure is brought to bear thereon, while any danger of the clips accidentally disengaging the lugs of the cap by falling or tipping over When released from the lugs of the jar, is positively pre- Vented.

' From the foregoing description it will be seen that a very simple and efficient jar sealer has been produced whereby, after the several elements have been placed in engagement With each other, the device may be tightened so that the spring portions thereof will be drawn into close binding engagement for positively sealing the ar and pre venting the accidental displacement of the several portions of the device.

What I claim is p H In a jar sealer of the class described, the combination of a body, slanting lugs formed upon said body adjacentone end thereof, a cap carried by the upper portions of said body for closing the same, a plate positioned above said cap, a set screw passing through said plate and engaging said cap, lugs formed upon the outer periphery of said plate and provided with longitudinal slots, spring clips carried by the lugs of said plate, each clip being formed of a single strip of resilient material being bent intermediate its ends to form a sleeve, said sleeves of said clips carried by the lugs of said plate, radiating arms extending from each sleeve and provided with alined apertures, said arms being normally spaced apart, said slanting lugs being adapted to be passed through said apertures, said set screw being adapted to be rotated so as to cause the lugs of said plate to draw upon said sleeves, whereby said arms of said clips will be drawn upon said slanting lugs so as to be moved together, whereby said top will be held upon said body, said arms being adapted to spring apart when released for facilitating their removal from said slanting lugs, said arms also preventing said sleeves from opening when pressure is brought to bear thereon.

In testimony whereof I hereunto aiiix my signature in presence of two Witnesses.
